Various myths surrounding sunscreen
Sunscreen or sunscreen is a cream that protects the skin from the sun, especially exposure to UVA and UVB rays. Both of them play a big role in contributing to the risk of skin cancer and other skin problems.
Quoting Sapna Patel, M.D, a lecturer assistant from Melanoma Oncology, here are the myths around sunscreen which you should no longer believe.
1. Dark skin does not need to use sunscreen
One of the myths sunscreen what is most often heard in the community is that dark skinned people do not need to use sunscreen.
This is because dark skin contains more melanin which reduces the effects of ultraviolet rays to some extent.
In fact, people with dark skin should also use sunscreen because the skin is equally unprotected from ultraviolet rays.
In fact, a study in the Journal of the American Academy of Dermatology stated that the survival of black people who have skin cancer is lower, compared to white people. These people include African-American, Asian-American, Native American, and Pacific islander races.
2. Sunscreen waterproof and only needs to be used once
In fact, sunscreen or sunblock that is resistant and waterproof also still needs to be reapplied on the skin after you get out of the pool or water.
Even though it is labeled waterproof, sunscreen it only protects the skin from the sun for a limited period of time. Each time you are exposed to water, the sunscreen protection on your body will also become thinner. That's why it's recommended that you reuse them every time you get out of the pool or after exercising.
Also, before plunging yourself into the pool, make it a habit to wait 10-15 minutes after using sunscreen so that it is well absorbed.
3. You don't need to repeatedly apply sunscreen with an SPF above 50
Many people think, the higher the SPF of a sunscreen, the longer skin protection they have. This myth makes them just use sunscreen just once a day.
In fact, the SPF number is printed on the packaging sunscreen only shows how much protection is provided, not how long it is.
Although sunscreen You have a very high SPF, over time it will continue to fade in 2-4 hours. That's why it's recommended that you wear sunscreen every 2-4 hours to maximize the protection of your skin.
4. No need to wear sunscreen when the weather is cloudy
Myth sunscreen the other is, he says, you don't have to wear sunscreen when the weather is cloudy or windy. When it is cloudy, the sun is not as hot as usual. This is what keeps this myth growing.
In fact, you are still at risk of exposure to UV rays because the light is not affected by the weather.
In fact, cloudy summer weather has the same UV levels when it's sunny. If you don't use sunscreen during the weather, you will likely be flushed from the sunburn.
5. Sunscreen makes the skin deficient in vitamin D
One source of vitamin D that humans need and easy to obtain is sunlight. However, when you use sunscreen,it makes it more difficult for your skin to get these nutrients, putting you at risk for vitamin D deficiency.
The theory is what increasingly "justifies" the myth sunscreen this one, so people are less likely to wear sunscreen for fear of vitamin D deficiency.
In fact, exposure to sunlight for a long time only increases the risk of skin cancer, not getting vitamin D.
What's more, sunlight can penetrate clothes and sunscreen it will lose its function over time.
Therefore, many dermatologists recommend spending 5-30 minutes in the sun a day to get enough vitamin D.
6. All types sunscreen same
Myths that all types sunscreen it is the same often makes people fooled and does not get maximum protection. In fact, there are many kinds sunscreen which are differentiated based on the material and the SPF.
Active ingredients in sunscreen such as titanium dioxide or zinc oxide are used to filter UV rays. In addition, it is highly recommended to use sunscreen with an SPF of more than 15 even in cloudy weather to protect you from the bad effects of the sun.
So, now you know that the various assumptions above are just myths about sunscreens that are not proven true. Use sunscreen when you have to be outside the house to get maximum protection. Don't forget to always read the usage instructions as each sunscreen have a different direction.
